Titanium or other biocompatible metal fibers having a diameter of from about 20 to about 200 .mu.m, a length of from about 2 to 50 mm and a length-to-diameter ratio of at least about 100 are formed into a flexible and deformable mass, for example, a sheet, of interlocked fibers, which may be sintered for additional coherence, to a thickness of from about 0.5 to 30 mm. The amount of fibers is such that the sheet has a voids volume of at least 65%, preferably about 90%. The diameter of the pores of the porous sheet are at least about 150 .mu.m such that bony tissue can grow in the pores. These porous sheets are highly malleable without loss of structural integrity or pore size distribution. Accordingly, the porous metal fiber mesh sheets are useful for stabilizing prosthetic devices or for general repair of defective bone structures.
A biocompatible flexible and deformable porous metallic fiber mesh sheet which is useful in reconstructive surgery, said sheet consisting essentially of a multiplicity of interengaged and intertwined biologically inert metallic fibers, each of said fibers having a length in the range of about 2 to about 50 millimeters, and a diameter in the range of about 20 to about 200 micrometers;
A biocompatible flexible and permanently deformable porous metallic fiber mesh sheet consisting essentially of a multiplicity of interengaged and intertwined biologically inert metallic fibers, each of said fibers having a length in the range of about 2 to about 50 millimeters, and a diameter in the range of from about 40 to about 100 micrometers;
A biocompatible flexible and permanently deformable porous metallic fiber mesh sheet consisting essentially of a multiplicity of interengaged and intertwined biologically inert substantially straight metallic fibers, each of said fibers having a length in the range of about 2 to about 50 millimeters, and a diameter in the range of from about 40 to about 100 micrometers;
